Fordomatic transmission fluid type A or F?
Time has passed me by in the types of fluids that the automatic transmissions now use. My 1957 Fordomatic uses type A transmission fluid according to the 1957 Ford service book. The Autozone parts house says that I should use type F or the GM/Ford fluid works too. When did they change from type A fluid to type F fluid? How long have they been combining the GM and Ford fluids? What works best in my 1957 Fordomatic transmission? My current transmission oil looks kind of red like the GM Dextron fluid used to look. What happens if one puts the wrong type of fluid in their Fordomatic transmission? Thank you for any help that you can give me.

Re: Fordomatic transmission fluid type A or F?
That sure helps. Currently, my 1957 Fordomatic has transmission fluid with the reddish color of the old type GM Dexron transmission fluid. Could this be the new multi-use transmission fluild available today? The transmission I was told, was rebuilt about 10 years ago. Maybe I should change the red fluid out and not take any chances?

Re: Fordomatic transmission fluid type A or F?
Dexron ll is supposed to be the replacement for the original Type A so I have heard. I used Type F with no problem.
I'm not even sure you can get Type A anymore. I think Ford started using Type F with the C-4/C-6, but not sure. |

i think time has passed by the Dexron TWO crowd also. NAPA has Dexron 3/Mercon. http://www.napaonline.com/Catalog/Ca...200_0006411566 Type F? Forget it! if you did find it, who's to say it's the original formula? Have A Nice Day!

stay away for 'Multi-Purpose', Dexron Type V ( 5 ) and something ? 'Plus 4' until further notice. it's down to Dexron/Mercon 2 or 3 ( II or III ). Have A Nice Day!

Re: Fordomatic transmission fluid type A or F?
Tonight I had just purchased 9 quarts of type F from AutoZone. I will take the fluid back and exchange them for the Dexron/Mercon 2 or 3 tomorrow. Since it has been about ten years since the Transmission rebuild, I won't take any chances, I will change the fluid out anyway. While I am at it, I will change out the fluid in our 1957 Bird at the same time. I had the transmission rebuilt in that one in 1978 and I haven't changed the fluid since in that one either. Both our cars are in the attachments. Thank you for the help. I was at a loss without the help of the "Ford Barn"..

Re: Fordomatic transmission fluid type A or F?

i would say err on the safe side and 'go ahead and take it back'. NAPA probably does have Type F if you walk in the store. i'm not much of a 'returner' myself. if you want to experiment use the F in one and the Dexron II ( 2 ) in the other. if you want to play it safe use all Dexron. Have A Nice Day!

Re: Fordomatic transmission fluid type A or F?
Looked for the 1957 Skyliner Retractable but I didn't see it. It is the only year that interests me. Our Skyliner is nice and the work is all done. One is enough at this time. Now it is time to change out the trans fluid next. I will forego the filter and pan gasket at this time.

NAPA does carry Ford Type F Trans fluid. We keep it in stock all the time.

i'll just say it, since we're fellow californians. it's a little better to change the filter too. part of that is washing 'filings' out of the pan. a new filter will give you better flow and pump will not have to work as hard. changing fluid only is good though. it's a good step. Have A Nice Day!

Re: Fordomatic transmission fluid type A or F?
Type F works very well with a early Fordomatic. My car has gone from NY to Oregon, NJ to Ohio and lots a local miles with Type F.

Re: Fordomatic transmission fluid type A or F?
Well, I changed out the transmission fluid in both of our '57 s today. The retractable only has 800 miles on its rebuilt transmission so the fluid was nice and clean looking yet. The new fluid was about two shades cleaner than what was drained out. I have no doubts about the filter still being clean in that one. The '57 T bird has about 10,000 miles on its rebuild and the fluid looked like dirty motor oil. Since it was in 1978 that it was last rebuilt, I tend to believe that I should have replaced its pan gasket and filter at the same time. You are right about changing the filters. I should have done it. With the time that both transmissions had on them, I am sure that their additive packages were well used up in both of them by now too.

Re: Fordomatic transmission fluid type A or F?
TYPE F fluid was not released until the 1968 model year. It was phased out in the early eighties (except for certain foreign applications and TYPE F specific steering fluid).
TYPE A is replaced by DEXRON III. MERCON (FORD) has been superseded by the fully synthetic MERCON V although the non-synthetic MERCON is still available from outside refiners. Rule of thumb; TYPE F can be generally used in DEXRON call outs but not the reverse. TYPE F will also give firmer shifts. |

we used to put Type F in Mopar 727's to tighten the shifts. word was though, it would wear out the clutches faster. since it's almost a 'preservation' thing going on with these Y blocks and Fordomatic's i think i'll use that Dexron III you recommend. have a nice day!

Re: Fordomatic transmission fluid type A or F?
Let me go further as there is a lot of confusion as to fluid type usage-
FOMOCO came out with TYPE F in the 1968 model run as they changed friction material used in clutches and bands to asbestos based. In the late seventies, there was a big push for the industry to get away from asbestos (brake lining materials mainly). FORD complied and went to using organic materials in their trans clutches/bands which was not compatible with TYPE F fluid. They went with their version of DEXRON (MERCON). As the TYPE F call-out trans were overhauled, it was usually with organic materials which called for DEXRON/MERCON (DEXRON being GM licensed, MERCON being FORD licensed). In short, one has to know if the trans has been rebuilt during it's service life and what type of friction materials were used. Rule of thumb again, TYPE F can be used in a pre-TYPE F trans with no damage but if you introduce DEXRON into a TYPE F trans, you are going to have trouble. B & M Trick-Shift is a TYPE F product. TYPE F (to the best of my knowledge- and it is limited) will not damage a TYPE A to D transmission (trans fluid progression before F). I believe also that GM's propitiatory rights to DEXRON III has expired and they went to DEXRON VI which is a full synthetic. The same story with FORD as MERCON V is a full synthetic and is backwards compatible (EXCEPT TYPE F trans). When you buy a bottle of DEXRON III, the refiner is not held to the original formula now so you have to be careful. I hope I explained this clearly but ask if any question or you have another theory. This is what I have found over the years.
